Energy-saving Solutions for Enterprise
◆Saving energy achieves 10% -70%
◆The enterprises do not need to pay for expense of equipment manufacture and installation.
◆Enterprises only need to pay the saving electricity expense to our company according to the actual quantity of energy saving after the equipments put into operation.
◆According thousands of the projects’ implementation experiences, such projects recover the investments in three or four years. (Equipment service life is 15 years)。
◆Our company will no longer charge the saving electricity expense after recovering the investment.
The significance of the program:
1）、Concentrate on solving problems of energy conservation, make enterprises’ energy-saving work reach new level and take their social responsibility。
2）、Avoid the enterprises reactive power fine of low power factor caused by electric energy using (according to Ministry of Electric Power and Water Resources, State Price Control Bureau establish the " measures of power factor adjustment expense ").
3）、Avoid the high-energy consumption enterprises are implemented differential prices because of the changes of national power regulation.
4）、For the standard-conforming large-scale (saved energy equal 10 thousand tons standard coal or more) energy-saving technological transformation projects, China will reward the enterprises for energy saving which based on the "Financial Incentives Interim Measure for Energy-saving Technological Transformations" established by Ministry of Finance, the National Development and Reform Commission.( Amount of 200 yuan / ton of standard coal).
5）、Equipments recovery period is generally 3-4 years, each period payment equal to the amount of current energy-saving benefits, and equipments service life are 15 years, so enterprises will gain huge energy-saving benefits.

- Q:How many types of CVT are classified?
- CVT (Continuously Variable Transmission) technology that is continuously variable technology, which uses the belt and the working diameter of the main and driven wheel to match the power to transfer, you can achieve a continuous change in transmission ratio, resulting in transmission and engine conditions of the most Good match
- Q:Will the laptop's power adapter is not the original good?
- See the adapter is suitable for notebook models to use, the following three conditions for reference:
1. The output voltage of the adapter is the same as that of the notebook.
2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.)
3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.)
- Q:Laptop power adapter problem
- Third, since the book is very old, the original factory may not have such a transformer spare parts, then a reasonable idea is to let this book off, rather than the provincial money to take their own little life joke, a notebook and then expensive It will not be more expensive than your life, the money is very unreasonable province. A notebook with a decade is also completely considered the best use of the matter, you are stingy stingy Ye Hao, there are emotional sustenance worth mentioning, it should be eliminated or out of it.
- Q:What is the difference between the collector and the emitter mode?
- While the base area should be very narrow
So bjt is not a symmetrical device
- Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
- Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;
- Q:What is the application of variable frequency speed control?
- Generally used in the need for continuous speed control of the place.
With the general exchange of motor than its advantages is able to continuously speed.
DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
- Q:What is the difference between AC and DC frequency converters?
- Inverter air conditioner is relatively speaking in terms of ordinary air conditioning, ordinary air conditioning compression motor using AC induction motor, speed unchanged, 50HZ when the speed is about 2880r / min. The inverter air conditioner is the first 220V, 50HZ single-phase AC into three-phase inverter AC (25 ~ 118HZ, 56 ~ 160), the supply of compressors, through the frequency changes to adjust the compressor speed, so that continuous cooling capacity to adapt to air conditioning Load needs. L inverter air conditioner works: inverter air conditioner compressor by the variable frequency motor drag, the power inverter output frequency changes in the alternating current to the motor, so that the motor speed can be based on the needs of indoor cooling and continuous change, the final compressor cooling capacity To achieve continuous changes in the automatic control. In order to meet the continuous changes in the cooling capacity, the refrigeration system uses an electronic expansion valve, the pulse motor switch valve core, rapid control into the evaporator refrigerant flow. Power frequency changes from the inverter to achieve, as shown in Figure 1: 220V, 50HZ of the mains input, the frequency converter A / D AC / DC conversion, D / A inverter, the output frequency required by the three-phase alternating current, Room switching power supply principle is similar.
- Q:Can the laptop's power adapter be used for years?
- Generally 3 to 5 years is not a problem, good quality can be used for 10 years.
Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop. Extensive support in the phone son machine, game consoles, language repeaters, Walkman, notebook computers, cellular phones and other equipment.
- Q:Inverter alarm a043, how is it
- When a signal failure occurs, use the DTI board, if necessary, change P215. With P806
(Follow the parameter description) during operation can be converted to no encoder operation
A043 is: n-actjump exceeds the allowable change speed of the speed encoder signal (P215)
In addition, for the synchronous motor (P095 = 12):
The motor speed is 2% higher than the inverter release time point.
The inverter in the ready state can not exit. Check processing:
Check if the cable is disconnected
Check the tachometer to shield the ground
Not only on the motor side but also on the inverter side
The encoder cable does not allow disconnection
Use only recommended encoders
The encoder cable is not allowed to be laid with the power cable
- Q:Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
- The current will be great ... ... a long time on the bad
